Flip-type electronic apparatus

Abstract

A flip-type electronic apparatus includes a base panel, a cover, and a latch mechanism pivotably fastening the cover to the base panel. At least one post extends from the cover into the base panel. The latch mechanism includes a button mounted on the base panel, and a sliding bar received in the base panel. At least one limiting portion is formed on one lateral side of the sliding bar receiving the post of the cover. The sliding bar forms a pair of inclined operating surfaces, and the button forms at least one inclined actuating surface abutting at least one of the pair of inclined operating surface. When the button is pressed, the actuating surfaces pushes the operating surfaces to cause the sliding bar to move away from the button, and thus the post is released from the limiting portion for opening the cover of the electronic apparatus.

1 . A flip-type electronic apparatus, comprising:
 a base panel;   a cover being pivotably connected to the base panel, at least one post extending from the cover into the base panel; and   a latch mechanism comprising a button mounted on the base panel, and a sliding bar received in the base panel and movably connected to the base panel, at least one limiting portion formed on one lateral side of the sliding bar for receiving the at least one post of the cover, the sliding bar forming a pair of inclined operating surfaces, and the button forming at least one inclined actuating surface abutting at least one of the pair of inclined operating surface of the sliding bar, wherein when the button is pressed, the actuating surfaces of the button pushes the operating surfaces of the sliding bar to cause the sliding bar to move away from the button, and thus the at least one post of the cover is released from the limiting portion of the sliding bar for opening the cover of the electronic apparatus.   
   
   
       2 . The electronic apparatus of  claim 1 , wherein the at least one inclined actuation surface of the button is a pair of inclined actuating surface and the pair of inclined actuating surface abuts the pair of inclined operating surface of the sliding bar respectively. 
   
   
       3 . The electronic apparatus of  claim 1 , wherein the pair of inclined operating surfaces of the sliding bar are parallel to each other. 
   
   
       4 . The electronic apparatus of  claim 1 , wherein a supporting portion is formed in a recess in the base panel, the supporting portion comprising a sidewall and a basewall, an operating hole being defined between the basewall and the sidewall for receiving the button, a notch being defined in the basewall, the actuating surfaces of the button extending through the notch of the basewall. 
   
   
       5 . The electronic apparatus of  claim 4 , wherein at least one cylinder extends from the basewall of the supporting portion, the button comprising at least one pillar extending into the at least one cylinder of the supporting portion. 
   
   
       6 . The electronic apparatus of  claim 4 , wherein a pair of barbs extend from the button through the notch of the supporting portion, and engage with the sidewall of the supporting portion to assemble the button to the base panel. 
   
   
       7 . The electronic apparatus of  claim 5 , wherein a board extends from the supporting portion and abuts the sliding bard to limit movement of the sliding barb. 
   
   
       8 . A latch mechanism of a flip-type electronic device for fastening a cover to a base panel of flip-type electronic device, comprising:
 a button comprising a button body, and two groups of blocks extending from the button body, each block forming an inclined actuating surface;   a sliding bar forming a pair of inclined operating surfaces, each operating surface abutting the inclined actuating surface of one of the groups of blocks of the button;   at least one limiting portion formed on one lateral side of the sliding bar, the at least one limiting portion being configured for engaging with a fixing portion of the cover; and   a spring being configured for movably connecting the sliding bar to the base panel of the electronic device;   wherein when the button is pressed, the actuating surfaces of the button push the operating surfaces of the sliding bar to cause the sliding bar to move away from the button, and thus the fixing portion of the cover can be released from the limiting portion of the sliding bar for opening the cover of the electronic apparatus.   
   
   
       9 . The latch mechanism of  claim 8 , wherein the each groups of block of the button includes two parallel blocks, each block forming an inclined actuating surface abutting the corresponding operating surface of the sliding bar. 
   
   
       10 . The latch mechanism of  claim 8 , wherein the pair of inclined operating surfaces of the sliding bar are parallel to each other. 
   
   
       11 . The latch mechanism of  claim 8 , further comprising a supporting portion having a basewall and a sidewall surrounding the basewall, an operating space being defined between the basewall and the sidewall for receiving the button body of the button therein. 
   
   
       12 . The latch mechanism of  claim 1 , wherein a notch is defined in the basewall of the supporting portion, the blocks of the button extending through the notch of the basewall to contact the operating surfaces of the sliding barb. 
   
   
       13 . The latch mechanism of  claim 12 , wherein a pair of barbs extend from the button body through the notch of the supporting portion, and engage with the sidewall of the supporting portion to assemble the button to the base panel. 
   
   
       14 . The latch mechanism of  claim 12 , wherein a board extends from the supporting portion and abuts the sliding bard to limit movement of the sliding barb. 
   
   
       15 . The latch mechanism of  claim 12 , wherein at least one cylinder extends from the basewall of the supporting portion, the button further comprising at least one pillar extending into the at least one cylinder of the supporting portion.
